Fix for phone in Safe Phone

I dropped my phone in a cup that had about 1 inch of liquid in it yesterday. This submurged the bottom 4 screen keys. I removed the battery and the SD card, and placed my phone in a bag of rice overnight to remove any traces of liquid still inside. I start my phone this morning, everything works fine, except the Menu and search keys, and it is in safe mode. I have heard that shutting it down while in safe mode has caused a boot up loop, and am afraid to do this since function of my phone is working (bluetooth, emails, call functions, etc). Any suggestions as to where to begin to correct my phone to full functionality?
Thanks much!
